Definitions

  • the present invention relates to a device including a mechanism capable of removably accommodating a memory card.
  • FIG. 16 shows in simplified form an example of a device with a memory card insertion/removing mechanism (refer to, for example, Japanese Unexamined Patent Application Publication No. 9-17493).
  • a device 40 can removably accommodate a memory card 41 , and has a memory card holder 42 and a card insertion unit 43 .
  • the memory card 41 is slidingly fitted and inserted into the card insertion unit 43 .
  • the card insertion unit 43 is mounted to walls of the memory card holder 42 so as to be rotatable in the directions of a double-headed arrow Tr shown in FIG. 16 .
  • the memory card 41 When the memory card 41 is to be inserted into the device 40 , for example, the memory card 41 is slidingly fitted and inserted into the card insertion unit 43 that is raised as shown in FIG. 16 . Then, the card insertion unit 43 is rotated in the direction in which it is tilted downward, and is accommodated in the memory card holder 42 . Thereafter, the memory card holder 42 is covered by a cover (not shown), and is sealed. This completes the insertion of the memory card 41 into the device 40 .
  • the aforementioned steps are carried out in the reverse order. That is, first, the cover is removed from the memory card holder 42 , and the card insertion unit 43 in the memory card holder 42 is rotated in the direction in which the card insertion unit 43 is raised. Then, the memory card 41 is removed from the card insertion unit 43 . In this way, the memory card 41 can be removed from the device 40 .
  • Japanese Unexamined Patent Application Publication No. 9-17493 refers to Japanese Patent No. 3120043 (Japanese Unexamined Patent Application Publication No. 10-162894) and Japanese Unexamined Patent Application Publication No. 2001-76101.
  • preferred embodiments of the present invention provide a device with a memory card insertion/removing mechanism having a simple structure and allowing easy insertion and removal of a memory card.
  • a device with a memory card insertion/removing mechanism includes a memory card holder for accommodating a memory card through a slot communicating with the memory card holder, a pushing-out member accommodated in a pushing-out member holder and movable in a card insertion direction and a card removing direction along a first guide defined by the pushing-out member holder, the pushing-out member holder communicating with a back side, as viewed in the card insertion direction, of the memory card holder, and an operation opening exposing a portion of the pushing-out member to the exterior of the device.
  • the pushing-out member is moved in the card insertion direction by the pushing force of the memory card when the memory card is inserted, and pushes out the memory card accommodated in the memory card holder by external operation through the operation opening.
  • the memory card holder functions as a second guide for guiding the memory card such that one of two surfaces of the memory card holder is facing at least one of two surfaces of the memory card.
  • the first guide has a top surface and a bottom surface and side surfaces therebetween, one of the top and bottom surfaces being disposed continuously and flush with one of the two surfaces of the second guide, the side surfaces guiding sides of the pushing-out member.
  • the device with the memory card insertion/removing mechanism of various preferred embodiments of the present invention is constructed so that the memory card can be accommodated in the memory card holder by inserting the memory card into the memory card holder from the slot, and can be removed from the device by pushing out the memory card from the memory card holder by the pushing-out member.
  • the insertion and removal of the memory card can be carried out by very simple operations.
  • the device with the memory card insertion/removing mechanism is constructed so that the pushing-out member can be directly operated through an operation opening which exposes a portion of the pushing-out member to the exterior of the device. Therefore, the memory card insertion/removing mechanism in the present invention does not require a complicated structure including, for example, a spring for moving the pushing-out member, so that it has a very simple structure. Consequently, it is possible to simplify the structure of the device and to reduce the number of parts, thereby making it possible to reduce the cost of the device. Further, it is possible to reduce the probability of failure of the memory card insertion/removing mechanism of the device, so that the durability of the device can be ensured.
  • a structure in which a fitting portion of the pushing-out member and a fitting portion of a side surface of the first guide or pushing-out member holder are fitted together makes the following possible.
  • the fitting portion of the pushing-out member and that of the side surface of the first guide are fitted together. This generates, for example, a click, and stops the pushing-out member, so that, for example, a tactile feel is transmitted from the pushing-out member to an operator, thereby making it possible to notify the operator that the pushing out of the memory card is completed.
  • the fitting portion of the pushing-out member and that of the side surface of the first guide are fitted together. This generates, for example, a click, and stops the pushing-out member, so that, for example, a tactile feel is transmitted from the pushing-out member to the operator, thereby making it possible to notify the operator that the insertion of the memory card is completed.
  • a flexible portion may be disposed at the side surface of the first guide or at a side of the pushing-out member facing the side surface of the first guide in preferred embodiments of the present invention. This makes it possible to smoothly move the pushing-out member by guiding it by the side surface of the first guide while deforming the flexible portion by pushing force produced by the fitting portion. In other words, it is possible to easily move the pushing-out member without exerting undue force on the pushing-out member.
  • the slot may have a similar size as an end of the memory card, and the operation opening for externally operating the pushing-out member exposes a portion of the pushing-out member to the exterior of the device. Therefore, it is possible to reduce the areas of the entire device that the slot and the operation opening occupy. This makes it possible to prevent a reduction in the strength of the device caused by the openings, so that the strength of the device can be ensured.
  • the pushing-out member can be more easily operated.
  • a protrusion which fits the cutout of the memory card is disposed on a portion of the pushing-out member that comes into contact with the memory card. Therefore, when, for example, the wrong side of the memory card is inserted by mistake, the end of the memory card contacts an end of the protrusion of the pushing-out member, thereby preventing the memory card from being inserted to the set accommodation position. Consequently, any person who has inserted the memory card can realize whether or not he/she has inserted the wrong side of the memory card. If the wrong side is inserted, he/she re-inserts the correct side of the memory card, and properly accommodates the memory card in the memory card holder of the device.
  • the memory card insertion/removing mechanism is a distinctive mechanism having a simple structure, so that it can be installed in a card device without increasing the size of the card device. Therefore, preferred embodiments of the present invention are very effective in providing a small, thin card device.
